Since I am sure all this is done automatically, I think the issue was the computer knowing correctly what order was issued, as opposed to just "when the order was given."
Let's imagine you were my broker, and in 2012 I told you I wanted you to distribute $1000 out of my account starting in 2014 - would you book a distribution in 2012 when I am not to receive the money until 2014. I would hope not. This is a gross exaggeration of what happened, but the technicality is I believe the same. What I did was a little before midnight on Dec 31st issue an automatic order for a distribution starting the 1st of every month (in this case the distribution happened on Jan 2nd because Jan 1st was a Holiday. Thus the distribution was not only executed in 2013, but the ordered execution date was in 2013 as well. The only thing that happened in 2012 was my decision to execute an order in 2013.
I love simulated data. It turns the impossible into the possible!
